How to find the difference between two times
Subtract the minutes of the earlier time from the minutes of the later time.
If the minutes of the earlier time are more than the minutes of the later time,
subtract 1 from the hour of the later time and add 60 to the minutes of the later
time. After you have found the difference in the minutes, subtract the hour of
the first time from the hour of the second time.
